Guardian Robe is the rarest thing I've ever farmed

[Trelaboon]

So I've really only been camping this thing for about 5-6 days, but between that time I've invested 50-60 hours (killin 10 mobs per cycle)

How many of you have actually camped the robe and how long were you there? so far it seems like it has a less than 1/1000 drop rate (thats about how many I've killed, maybe a bit more). I always wondered why I never saw people wearing it; I guess now I know why.
